Going back to school

In two weeks, I will be back to school. I was absent for a month because of being hospitalized and sick but I still passed all my subjects, so thank God! But the thing is, they will see how bad I look now. How would I manage this? Even when I am alone at home, I feel ugly. Sunlight is my enemy and my classes are scheduled at morning. I will be looking for internships this semester and I've got VERY low self esteem now.  I am panicking. I am stressed. I am afraid. I've never been this afraid. I am afraid of how sad I can even more be. I mean, it would be like 10x the pain. I can not even imagine that knowing how painful it is just being here at home. 
 
I know that God will walk me through this. I've just got to hold on, keep my motivations in mind, and trust His plans.
